Definitions

  • a metal cylindrical liner is driven in the soil to act as an anti-collapsible support, as the earth is removed from inside by the drilling machine.
  • the earth is drilled inside a large pipe which becomes the wall of the hole drilled.
  • the drilling operation has to be interrupted when the depth reached is the same as that of the liner so that the same can be driven further down by means of a second liner which is fitted and pushed over the first and the drilling operation can continue inside the first liner buried in the soil.
  • the wall of the hole drilled consists of a set of superimposed cylindrical liners, suitable for preventing the earth from collapsing, because of its inconsistency, inside the hole.
  • Each liner is currently driven in the earth by means of special machines consisting essentially of a bearing trellis supporting a vibrator at a certain height capable of supporting the liner in a perfectly vertical position and of hitting it repeatedly down so as to allow the liner to penetrate gradually in the earth.
  • the purpose of this invention is to eliminate all the problems caused by the alternated and repeated use of the above two machines, by designing a vibrator which may be installed directly on the "rotary" of any drilling machine, so that drilling times are minimized considerably.
  • the device according to the invention includes a vice for gripping the liner at two diametrically opposed points of the edge; the liner being fixed at the bottom to a casing in which the vibrator is housed, consisting of a symmetrical pair of revolving shafts, having the same RPM, on which eccentric masses for creating a vibrating movement are splined.
  • This casing is suspended from the fixing flange of the "rotary" of the drill by means of a series of annular rubber pads which act as shock absorbers to prevent the vibrations of the casing from being transmitted to the "rotary".
  • the vibrator according to the invention includes a double vice for gripping the edge of a liner, in vertical position, at two diametrically opposed points.
  • This double vice consists of two coaxial and opposing hydraulic cylinders (1), each of which is fixed under a respective support block (2) sliding inside a box-shaped guide (3), fixed firmly under a plate (4), which forms the back wall of the casing containing the actual vibrator.
  • each hydraulic cylinder (1) on being expelled press on the external edge of the liner, whose internal edge touches a vertical tooth (2a) projecting at the bottom of the sliding block (2).
  • the stop position of the sliding block (2) inside the box-­shaped guides (3) can be varied so as to adjust the distance of the teeth (2a) which must fit into the edge of the liner, according to the diameter of the liner to be gripped.
  • the two box-shaped guides (3) are fixed on diametrically opposite sides, under a plate (4) with a central opening (4a), which closes the casing (5) which contains the vibrator, at the bottom.
  • This casing is closed at the top by a counter-plate (6) which must have a wide central opening, like the underlying plate (4), for the passage of the set of rods supporting the drilling tool which digs inside the set of overlying liners driven in the ground.
  • An annular platform (7) which is suspended, by means of a number of support and fixing U-bolts (8), at the bottom of the flange (9) fitted outside any "rotary", is fitted over and spaced from the counter-plate (6).
  • the counter-plate (6) and the annular platform (7) are connected together by means of an annular series of vertical and opposed pairs of plates (6a and 7a), between which a pad (10) in shock absorbing elastic material, as for example rubber, is fixed so that the annular platform (7) is not affected by the vibrations of the counter-plate (6).
  • Two hydraulic motors (11) are fitted outside the two transverse sides of the casing (5) for rotating the respective shafts (12), on each of which a gear (13a) and an eccentric mass (14a) are splined, which creates the vibrating movement of the casing (5), together with another eccentric mass (14b) splined to an intermediate shaft (12a), parallel and fitted next to the main shaft (12), and rotated by the above gear (13a) driven by a geared wheel (13b) splined to the shaft (12a), the gear ratio being equal to one.
